The Wood Panels that Showed Japanese Cars at Their Peak

　If you were asked what the most

vital thing in a luxury car is, what

would you answer? Air-conditioning?

Leather seats? The audio system?

　Each answer may be correct, but all

these things can be found in mass-

produced compact cars. What gives

a dignified impression are the wood

panels in instrument panels, door

The wood panels and steering wheel inside many luxury cars are made in northeast Japan with the latest technology.

Japanese craftsmanship is recognized worldwide.Let's see the work that Niche craftsmen achieve.

The Progressive Spirit and Proud CraftsmanshipThat Made Wood into a Refined Industrial Product

Tendo WoodworkCorporation

Niche Craftsmanship—①

The but t er f l y s t o o l s designed by Sori Yanagi are displayed in museums throughout the world. These stools fully use the characteristics of the molded plywood.

　Tendo Woodwork, a furniture

manufacturer in Yamagata, made this

possible. The key is molded plywood

technology. This technology produced

the butterfly stools (1956) designed

by Sori Yanagi, which are displayed

at the Museum of Modern Art in New

York.

The Latest Technology of an Artisan Spirit That Handles Woods Freely

　Tendo-city in Yamagata prefecture

is famous for the production of shogi

(Japanese chess) pieces. This tradition

started as work done at home by a

samurai in a snow-bound winter,

and continues to be the industry of

handicraft manufacturers throughout

the city.

　The place is also popular for

producing w o o d w o r k , s u c h a s

furniture, f itt ings, cabinetwork

and lacquer wear using wood from

Ouu Mounta ins and Shirakami

Mountains. To overcome the lack of

trims and steering wheels, which

are only available in real luxury cars.

The wood panel is not fake, not resin

covered with a wood pattern. It is real

wood with a unique, attractive wood

grain.

　Wood panels were originally used

for the interior of carriages and

luxury cars of Europe. Ten years after

WWII, Japan started mass-producing

domestic cars, but they could barely

stand up to practical use. Even the

luxury cars were of poor quality, with

metal parts exposed at various places

inside the vehicle. To use wood panels

in the interior of Japanese cars was

only a dream.

　In the 1960s, high-grade sports cars

with wood-panel interiors appeared

in Japan. But the wood panels were

possible only because few were

produced. At that time, wood panels

were crafted products. They were

not “automobile parts” in the true

meaning; they couldn't satisfy the

conditions required for cars today.

True, the cars didn't have exposed

metal parts, but Japanese cars still

used the wood-looking panels of resin

for the interiors.

　In 1987, the long-awaited Japanese

car equipped with real wood panels

appeared. When the Japanese

automobile manufacturers reached

the i r peaks economica l l y and

technically, they aimed to develop a

high-grade car that could challenge

foreign brands face-to-face. They

succeeded in mass-producing wood

panels that are of higher quality,

more durable and more attractive

than traditional brand rivals.

The wood panels (upper photo) and steering wheel (lower photo) that Tendo has been working on. Today, company representatives go all over the world in pursuit of beautiful walnut wood with beautiful grains.

Thin sheets of wood are placed on top of each other in a model, and then are molded and adhered together by the pressure and heat of a pressing machine. The characteristics of wood are not regular. The craftsman can make the products uniform by delicately adjusting the temperature and pressure. The combination of adhesives also changes according to the temperature and humidity of the day.

and surface materials.

　To refine this technique (which he

learned at the National Industrial

Arts Institute in 1947), Tokukichi Kato

installed a high-frequency oscillation

instrument in the Tendo factory, a

first for a private enterprise. He then

began full production of furniture

using the molded plywood. The

instrument cost 250,000 yen, a large

investment at the time.

　“The second president of our

company, Fujitaro Oyama, said that

we've bought a toy for the factory

manager,” laughs Noritoshi Kato, the

deputy manager of the production

department. “Since then, we never

got blamed for a failure that results

from challenging a new technique.

W e g e t t h e

instruction to

‘do i t ,’but

never an order

to ‘stop i t .’

That's our corporate

culture.”

　Thei r a t t i tude and

skill f irst captured the

attention of the Japanese

industrial designers and

architectural pioneers,

such as Isamu Kenmochi,

Sori Yanagi and Kenzo

Tange , who had a

c o n n e c t i o n w i t h

Tendo at the National

Industrial Arts Institute. Tendo's

products were designed by these

pioneers, starting with the chairs by

Kenzo Tange designed for the Ehime

prefectural hall in 1953. Over the

years, other products designed by

resources before WWII, the Tendo

Woodwork Manufacturing Guild was

established in 1940. This guild was the

predecessor to the Tendo Woodwork

Corporation.

　 D u r i n g t h e

W a r , T e n d o

workers produced

ammunition boxes and

wooden decoy planes.

After the War, the company

started making furniture again.

　Yukio Fukushima, the director

and the planning manager,

said: “From the start, we

were a group of craftsmen.

Tokukichi Kato, the factory

manager, had a strong

craftsman spirit. He never

said that we could not

make something; he

tried creating difficult things. As a

result, he succeeded in producing

molded plywood, a state-of-the-art

technique at that time.”

　Molded plywood is made from a

technique in which thin sheets of

sliced wood are placed on top of each

other in a model and then adhered

together by the pressure and heat

of a pressing machine. The plywood

can be made into any desired form.

This technique was developed at the

National Industrial Arts Institute,

which was established in 1928 to

produce Japanese products that could

be accepted overseas. During the

War, this technique was also used

for making propellers for fighter jets.

Using this technique, there is less

material waste than when shaving

pure wood, and light but strong and

homogeneous products can be made

from the molded plywood. What is

more, strong and beautiful products

can be created by changing the center

Planing wood for the large meeting table, a special order. Other manufacturers may use a sanding machine for efficiency but, at Tendo, the wood is planed by hand. This is the craftsman spirit.

These beautiful mushroom stools are molded so exquisitely that it took about 40 years for the design to get turned into form.

these pioneers have been installed

into public facilities, companies,

hotels and hospitals. They also

designed beautiful furniture, such as

the butterfly stools and mushroom

stools , which are d isplayed in

museums around the world.

　Today, Tendo furniture is used in

many facilities, such as the Imperial

Household, the National Diet Hall,

the Metropolitan Assembly Hall, and

the Congress Building in Brazil. As it

perfectly materialized the inspiration

of the first-class designers, their

molded plywood technique spread all

over the world.

　“Furniture in public facilities must

never break. Therefore, we not only

shape the design according to plan,

but also thoroughly examine the

materials and method and make

the best use out of the wood's

characteristics. Our products for

general use are made with the same

technique and quality as are our

custom products, so they can be used

for a lifetime,” says N. Kato proudly.

　However, this technique was not

known among car manufacturers,

and Tendo workers did not think that

car manufacturing was an area for

their talents. What brought the two

together was a single phone call.

Only When You Have the Full Knowledge of the Wood Can You Make a Masterpiece

　One day in 1987, Y. Fukushima,

a young salesman, took a phone

cal l f rom an engineer of a car

manufacturer.

　“He asked if we could make the

first mass-produced wood panels for

cars in Japan. I wondered if it would

be right to accept the job. I asked the

engineering managerand he said it

was OK.”

　At that time, the car engineer

wanted to use real wood panels for

the luxury car he was developing. He

visited many furniture manufacturers,

but was turned down. He was at a

loss when he finally phoned Tendo.

　The plan he showed was of a simple

flat shape. The craftsmen thought

that it could be easily made using

the plywood technique in which thin

sheets of wood are laid on top of each

other. However…

　“Half the first test models we

delivered were returned,” said Keiji

Sato, the section chief of the producing

engineer . “Furni ture can have

an error of +/-0.5mm, but for the

wood panels used in cars , we

were required to have an accuracy

of +/-0.1mm. What's more, cars

are lef t outs ide and the cabin

temperature ranges from -30 ℃ to

70℃ . Durability under such severe

conditions is required. It was an

improbable requirement in case of

wooden furniture.”

　But Tendo would not give up. They

utilized the techniques they learned

through making furniture, such as the

formulation of the center material,

the combination of adhesives, and

the pressure and temperature of

the pressing machine. Finally they

succeeded in making real-wood

panels for mass-produced cars, a first

for Japan.

　Their reputation drew many orders

from various manufacturers but a

higher technical level was needed.

“First, only wood was used, but then it

Tendo is proud of this steer ing wheel with the wood grain running horizontally (“shimamoku”; beautiful, high-end synthetic wood trim). It cannot be made by any other manufacturer.

The Orizuru (a folded paper crane) chair of the origami (the art of folding colored square paper into various figure) motif was designed by Ken Okuyama, a famous car designer. This is an example of the extreme flexibility of the molded plywood.

6 FIND Vol.31 No.1

changed to using die-cast aluminum

for the base and covering it with

wood, and then the base changed to

resin. The shape changed too. First it

was flat, but gradually began to have

complicated curves. We developed

adhesives that would adhere wood

strongly to different materials and

the technique to adhere wood to

complicated shapes.”

　K. Sato says that now their technique

is the number one in the world. “We

have the patent for the technique that

adheres wood directly to the resin base

of a complicated three-dimensional

shape. During that process, we made

more than 200 test models. We still

have challenges, but we want our

customers to admire our work, and

that makes us do the best we can.”

　These techniques do not end with

wood materials. The sharp-looking

carbon panels used in Japanese

high-end sports cars are produced

by applying the same techniques.

　The latest path-breaking work is a

steering wheel that takes advantage

of a unique wood texture of striped

grains called “shimamoku.”

　A conventional wood steering wheel

is made by bending the cylindrical

wood into a grip, like the handle of an

umbrella. In this way, the wood grains

are curved along the round shape of

the steering wheel. But to match the

horizontal basis of the indoor panel

design, the Tendo steering wheel has

wood grains running horizontally. For

that, they use a method in which the

sliced wood is adhered to the grip, like

leather wound around the steering

wheel.

　Leather stretches when pulled, but

even when thinly sliced, wood does

not stretch. Adhering wood tightly to

the whole circumference of a three-

dimensional curved surface, such as

the grip of a steering wheel, seems

to be physically impossible. K. Sato,

a skilled wood engineer, said: “The

car manufacturer said that we could

have small cuts on the wood, but

any woodworker can do that. We

racked our brains for months about

how to do it without having small

cuts.”

　Logically it is impossible. With

technique alone, it is impossible.

But one day, this impossibility was

solved. Of course, the technique

is confidential. These car parts are

produced at a dedicated factory where

outsiders are restricted.

　“Wood is a difficult material for

industrialization in the true meaning

of the word,” said N. Kato. “Woodwork

can only be finished using the skill of

an experienced craftsman. Otherwise,

we wouldn't be needed. We continue

to challenge the new techniques that

only companies with full knowledge

of wood (like Tendo) can achieve, and

to respond to requests from various

manufacturers and designers,” said N.

Kato.

　The wood panels, which are made

in Yamagata by craftsmen with the

artisan spirit, experience and skills,

are now available in sophisticated

Japanese cars in use all over the

world.

At the furniture factory, from left, Keiji Sato, Yukio Fukushima, Noritoshi Kato. The technique for developing wood panels and wood steering wheels is confidential and is never taken out of Tendo. The products are produced at a dedicated factory where outsiders are restricted.

In 1947, Tendo started producing molded plywood furniture by installing a high-frequency oscillation instrument. They realized shapes that are impossible to create when pure wood is used, and they worked with many top designers such as Kenzo Tange, Sori Yanagi and Isamu Kenmochi. In 1987, Tendo started p r o d u c i n g w o o d p a n e l s f o r m a s s -produced cars for the first time in Japan.

“OMNIVIEW,” a 360°wraparound view system that ensures the safety of EVs, which are bound to be major players soon

　The SIM-Drive Corporation specializes

in the development of EVs. The company

was founded in 2009 by Mr. Hiroshi

Shimizu, professor emeritus at Keio

University. Professor Shimizu has been

studying EVs for 30 years as a key way

to tackle environmental issues. In 2004,

he unveiled an eight-wheel EV, “ELiiCA.”

This car showed the public the great

potential of EVs with its outstanding

performance, including a top speed

of 370km/h and a range per charge of

300km.

　The SIM-Drive Corporation was

founded with the aim of developing

technologies for mass producing EVs.

Thanks to the cooperation and investment

of organizations participating in its

Advanced Development Projects, SIM-

Drive successfully launched Prototype

Model No. 1 “SIM-LEI” in 2011 and

　On March 27, a unique new car was introduced at the Tokyo Prince Hotel. The car, SIM-CEL, was developed by SIM-Drive Corporation, which focuses on the development of advanced mechanisms for electric vehicles (EVs). 　At the event, SIM-CEL's outstanding performance generated a lot of attention partially because it defies the stereotype of EVs. First, its elegantly designed exterior results in a superior aerodynamic performance, with a Cd (coefficient of drag) value of 0.199. Second, it accelerates from 0-100 km/h in only 4.2 seconds. Finally, it is in the world's top class of energy efficiency, with a driving energy consumption of 91.2Wh/km.　FUJITSU SEMICONDUCTOR's 360。Wraparound view system, “OMNIVIEW,” has been mounted on this vehicle thanks to the recommendation of mitsuiwa corporation. Mitsuiwa, one of our distributors, has been working with SIM-Drive since its first project. OMNIVIEW supports the safe and comfortable driving of the SIM-CEL.

360。

Wraparound View System“OMNIVIEW” Supports the Safe and Fun Driving of Innovative Electric Vehicles

Prototype Model No.2 “SIM-WIL” in 2012.

SIM-CEL is the project's Prototype Model

No. 3.

　Each prototype has a different concept,

namely a family car for golf lovers in their

50s, a city car that enables smooth driving

in urban areas for a couple in their 30s,

and a two-seater sports car designed

to enable “smart transportation” in

coordination with a “smart house” (an

all-electric house with an in-house power-

generation system). All the prototypes

use SIM-Drive's core technologies (in-

wheel motors and a component built-

in frame) that were first developed for

ELiiCA.

　Mr. Hideo Arai, Acting General Manager

of the In-Wheel Motor Development

Division of SIM-Drive Corporation,

explained the advantages of the

company's technologies. “With our in-

wheel motor technology, the tires of the

car are driven directly by motors inserted

inside the wheels, so there is no need for

an engine that takes up a lot of space.

Therefore, the car can have a large

cabin space despite its compact exterior,

and innovative ideas can be used in its

design. The car is also light and energy

efficient, as it doesn't have a transmission

or a driveline.”

　EVs currently on the market replaced

the internal combustion engine with an

electric motor. A speed reducer placed

between the motor and the driving

wheels acts as a transmission, a design

similar to that of gasoline cars. Therefore,

the essential advantages of EVs are not

fully utilized.

　SIM-CEL is also enjoyable to drive.

Since motors are installed in all its

wheels, the car has high skid resistance

and powerful acceleration, just like

a super-car. The component built-in

frame, which stores the large-capacity

lithium-ion battery underneath the

vehicle's floor, is the reason for the car's

large cabin space. At the same time, the

built-in frame gives the vehicle a low center

of gravity, offering brisk driving and a

comfortable ride.

　Mr. Arai said that “If we were to compare

a gasoline car to a feature phone, our EV

would be like a smart phone. Significant

advances have been made because of

completely new ideas.”

　Mr. Hiroyuki Suzuki, Executive Officer

of the Electronic Device Division of

mitsuiwa corporation, played a major

role in introducing OMNIVIEW to SIM-CEL.

“SIM-CEL is such an innovative car, all

its features need to be controlled by the

most up-to-date system. To make that

possible, I felt I needed to recommend

OMNIVIEW to SIM-Drive,” he said.

　Of course OMNIVIEW wasn't adopted

merely to make the car look “cutting-

edge.” Our product plays an essential role

in SIM-CEL.

　EVs can be driven quietly, since they

don't have a noisy internal combustion

engine. This can be a problem, in that

they are less noticeable to pedestrians.

Therefore, drivers must precisely know

the surroundings and be committed to

driving safely. “In that sense, OMNIVIEW

plays an important role, since it offers a

360。

wraparound view of the vehicle and

allows the driver to change the point of

view as desired,” said Mr. Suzuki.

Appeal to the public with an innovative EV that features completely new concepts and ideas

　OMNIVIEW displays a video image of

the car's surroundings on its monitor.

Video images taken by the cameras

mounted on the front, back and sides

of the car are synthesized using our

company's original image-processing

technology. Said in the next paragraph.

The latest version of OMNIVIEW, which is

used for SIM-CEL, includes every option

and feature available at the time, with

the aim of enhancing the innovativeness

of the car.

　Video signals sent from the four

cameras are processed at an extremely

high speed of 33ms. As a result, a near-

real-time image can be displayed on the

On March 27, a launch event for SIM-CEL was held at the Tokyo Prince Hotel.

At the launch event, the Model No.1 SIM-LEI (far right) and the Model No.2 SIM-WIL were also displayed.

As explained by the name “in-wheel motor,” the motor is installed inside the hub where the wheel is mounted. The motor directly moves the tire without the use of devices such as a speed reducer. This means that bulky mechanisms, such as a propeller shaft, can be eliminated from the space underneath the vehicle’s floor, and a component built-in frame that installs the lithium-ion battery underneath the floor can be used.

driver's monitor, even during high-speed

driving. This allows the driver to confirm

the safety of the car from all angles,

similar to looking in a mirror. Also, the

driver can freely change the point of

view. In the case of SIM-CEL, OMNIVIEW

provides the driver with completely new

views, including the view from the upper-

front of the vehicle, which clearly shows

the position of the car in relation to its

surroundings. The system also provides

the driver with a view from the side-rear

viewpoint, which allows the driver to look

at his or her “blind spots.”

　These kinds of futuristic video images

clearly show that SIM-CEL and OMNIVIEW

are ahead of their time.

　One advantage of OMNIVIEW is its

versatility, which allows for the use of

both analog and digital cameras. For

SIM-CEL, megapixel digital cameras with

1.2 million pixels offer a realistic view

through crisp, high-resolution images.

　Aerodynamically designed vehicle bodies

are efficient, but have a shortcoming,

in that they create more blind spots.

OMNIVIEW, with its clear, user-friendly

images, compensates for that weak

point. The system automatically displays

a view of the blind spots when the turn

signal is flicked on. In order to pass car

inspections under current regulations,

SIM-CEL also has side mirrors. “However,

I believe that there will come a time

when all protrusions will be eliminated

from a car's body, and drivers will check

the surroundings through the use of

systems like OMNIVIEW instead of

mirrors,” says Mr. Arai.

　“For SIM-CEL, we recommended the

adoption of the upper-front point of

view, which overlooks the entire vehicle,

because it provides a view that is like

a combination of the sights seen on

conventional rear-view and side-view

mirrors,” he said. However, at first, there

was controversy about adopting this

unique point of view.

　“I felt that we had to have this point of

view in order to show the innovativeness

of the EV. However, some people thought

users might feel uncomfortable, since

such a view is not available in conventional

cars. I argued that this is not a conventional

car, and we were finally able to adopt this

point of view.”

　It is typical for disagreements to arise

when new mechanisms and concepts

are introduced, because, by nature, they

are innovative. “We believe that, one

day, many customers will understand

and accept the unique viewpoints made

available by OMNIVIEW, along with the

other attractive features of the SIM-CEL,”

said Mr. Arai.

　SIM-CEL has another feature that

further expands the attractiveness of an

EV. The selling point of our company's

EVs is the fun feeling achieved through

the combination of a large cabin, the

exhilarating performance and comfortable

riding experience. To visibly portray this

fun feeling, a function changes the color

of the car displayed on the monitor

according to the driving status.

　The car is displayed in “white” while

driving normally, “red” while accelerating

and “green” while the motor regenerates

kinetic energy like a power generator

during deceleration. Through the energy

gauge, which is displayed inside the

speed meter, and this fun color-change

feature, people can enjoy driving as if

they're playing a game.

　“There is still a general misunderstanding

that EVs are slow and that drivers don't like

driving them. However, that is not true

with SIM-Drive's EVs, and OMNIVIEW is

proof that their EVs offer an enjoyable

driving experience,” explains Mr. Suzuki.

　““SIM-CEL” can accelerate quickly,

generating 0.7G at full acceleration, just

like a super-car. OMNIVIEW has made it

possible for users to visually realize the

car's high specifications in a fun way.”

Overcoming obstacles to installing the system with exceptional skills and extensive support

　SIM-Drive has continuously chosen our

products thanks to the recommendation

of mitsuiwa corporation, one of our

distributors, which has been participating

in SIM-Drive's projects since the time

the Model No.1 “SIM-LEI” was being

developed. Our graphics SoC “Jade” is

mounted on SIM-LEI's high-definition

graphic meter. “Jade” is used to beautifully

show vehicle information and rear-view

images on the 19-inch display mounted

on “SIM-LEI.” The large display is made

possible because of the EV's high space

efficiency. With the Model No. 1 “SIM-

LEI” and Model No. 2 “SIM-WIL,” the

side and rear cameras were controlled

by separate systems. However, with

the Model No.3 “SIM-CEL,” SIM-Drive

has installed a system with integrated

control.

　Like all other products, as the quality

of SIM-Drive's EVs improves, the functions

and performance of the devices installed

in the car also need to become more

advanced. As a result, it becomes

increasingly difficult to actually mount

　Since OMNIVIEW synthesizes video

on the highest possible, equally spaced

positions. However, since SIM-CEL is a

two-seater sports car, it has only small

side mirrors on the front part of the

vehicle. It is impossible to install cameras

inside such small mirrors.

　To tackle this problem, small protrusions

that do not hinder the aerodynamic

performance of the vehicle were attached

to the places where side marker lamps

are normally installed, and the cameras

are housed in those protrusions. The

protrusions are placed in low positions

toward the front of the vehicle. The

camera that films the front view was also

mounted on a low part of the vehicle,

specifically, the lower part of the front

bumper.

　FUJITSU SEMICONDUCTOR's skills were

fully utilized in the calibration process,

which uses software to reproduce a

natural view. It does this by enhancing the

images sent from the cameras, which are

located in positions that are far from ideal.

　Mr. Arai said: “We are satisfied not

only with the processing speed of

OMNIVIEW, but also with the cooperation

and support we are receiving from

FUJITSU SEMICONDUCTOR. Thankfully,

OMNIVIEW has become one of the major

features that visually reflects SIM-CEL's

innovativeness and high specifications.”

　All technical data obtained through

the development of SIM-Drive's EVs are

accumulated as resources at participant

companies, so that they can be used to

make the mass production of such EVs

feasible in the near future. “We strongly

believe that by the time we start to see EVs

running around the city instead of gasoline

cars, our OMNIVIEW will play an important

role in offering a fun driving experience to

drivers by replacing mirrors, which have

many blind spots,” said Mr. Arai.

The side cameras are placed under small protrusions, which do not hinder the aerodynamic performance of the vehicle.

MB86R20 Series

Introduction

　In order to increase the environmental

friendliness, safety, relief, and comfort

of automobiles, there is an increasing

need for “Integrated HMI (Human -

Machine Interface) Systems” that are

windows of information linking together

people, automobiles, and the world,

and the need is also increasing for

“360。Wraparound View Systems with

Recognition Functions” that warn

without fail about dangers surrounding

the vehicle in a 3-dimensional manner.

　The “MB86R20 series” third-generation

graphics SoC, compared to the second-

generation graphics SoC of the

“MB86R10 series”, has its CPU and GPU

performances increased by 2 times

and 5 times, respectively, and also has

6 video inputs and 3 display output

functions all available at the same

time. Further, systems with one-stop

procurement of all necessary items and

with lesser number of man-hours can

be developed because the necessary

software is also provided along with the

chips.

Integrated HMI Development Flow

　In order to experience driving that

is environment-friendly, safe, relief,

and also comfortable, the amount of

information linking people, automobiles,

and the outside increases dramatically.

Now-a-days, such information spans

various aspects such as battery

information of electric vehicles, vehicle

fault diagnosis information, image

information from cameras, warning

information, navigation information,

smart-phone-linked information, and

cloud-linked information, and so on.

　Until now individual display control

was being made of such information

using the center display, cluster

display, head-up display, etc. (Figure 1).

However, in order to transfer information

in real time and in an easy-to-understand

manner between the driver and the

vehicle, it is necessary to aggregate all

such information in one location and to

carry out centralized control of how the

information is portrayed to match with

the driving situation. This is done by an

integrated HMI system, and this trend is

considered to accelerate as the harmony

among people, automobiles, and the

environment increases.

　The MB86R20 series has a high-

performance CPU/GPU, 6 video inputs,

and 3 display output functions available

all at the same time, aggregates video

information from various sources such

as a system of cameras, head unit, etc.,

and carries out appropriate display

control of the center display, cluster

display, head-up display, etc. to suit

the driving situation (Figure 2).

　In addition, in an integrated HMI system,

each display section is modularized and

platformed, which not only greatly

reduces the component count but also

makes it easy to extend the product

to other vehicle types.

MB86R20 Series Graphics SoC Ideally Suitable for Integrated HMI Systems and 360°Wraparound ViewSystems with Recognition FunctionsThird-Generation Graphics SoC has high performance CPU/GPU, 6 video inputs, and 3 display output functions.In addition to high graphics rendering performance, these devices come with exhaustive software tools which make them ideally suitable for the development of integrated HMI systems and 360。 wraparound view systems with recognition functions.

MB86R20 Series

Strengthening CPU and GPU

　Two ARM®CortexTM- A9 are used

as the CPU. POWERVRTM SGX543 is

used as the 3-D graphics engine, and

compared to the second-generation

SoC’s of the MB86R10 series, the CPU

performance has been increased to

about 2 times, and the GPU performance

has been increased to about 5 times.

In addition, at the same time, our

company’s excellent 2-D graphics

engine realizing warping-on-the-fly,

etc. has been installed. Because these

operate independently, a much higher

performance has been obtained.

Multiple video inputs andstrengthening of display outputs

　This series is compatible with 6

full high-density video inputs and 3

video outputs. High resolution camera

images can be input implying that high

resolution contents can be input, and

outputs can be made to several high

resolution displays.

Rendering performance exceeding the specifications

　In addition to simultaneously operating

2-D engine, 3-D engine, and video

capture, by having 8 rendering layers,

optimum image processing can be

done on different rendering layers to

suit the application or the contents.

For example, by 2-D/3-D processing

of the rendering of the needle in the

cluster display and of the rendering of

the vehicle in different layers, a rendering

performance is obtained that is higher

than the specifications (Figures 7 to

Figure 9).

Automotive grade

　The high reliability has been realized

meeting the demands in automobile

and other fields.

Exhaustive Set of Software Tools

　For integrated HMI systems, the

authoring tool “CGI Studio” is provided

so that the contents design can be done

by the designer and the engineers by

cooperative design (Figure 10). Using this

tool, not only the performance of the

MB86R20 series can be brought out to

the maximum extent, but also because

of cooperative design by the designer and

the engineer, the contents visualized by

the designer can be reproduced instantly

on the MB86R20, and reworks in the

middle of merchandizing get reduced.

　For the 360。wraparound view system

with recognition function, in addition

to the conventional set of software

tools for 360。wraparound view system

(Figure 11), software products will

Towards Further Safety and Security (360°wraparound view system with recognition function)

　In a 360 。wraparound view system,

the entire surroundings of the vehicle

can be checked clearly and also from

any viewpoint by 3-D processing of the

images from 4 cameras installed at the

front, rear, left, and right of the vehicle.

Systems using the MB86R10 series

devices, which are second-generation

SoC, have already been introduced in

the market and are starting to spread

worldwide (Figure 3).

　The MB86R10 series can accept not

only analog cameras but also mega-

pixel digital cameras, whereby the

surroundings of the vehicle can be

portrayed as very clear images (Figure

4). Along with the proliferation of this

system, the demand is not only for the

ability to visually verify the surroundings

of the vehicle but also for new functions

that reduce items overlooked by the

driver.

　The third-generation SoC of the

MB86R20 series has much higher

performance CPU/GPU, and it has been

possible to realize both checking of

the surroundings from any viewpoint

and reduction of oversight by the driver

due to object recognition (Figure 5).

In addition, since 6 camera images

can be handled at the same time, the

concerned scene can be enlarged and

the degree of freedom of portraying the

3-D image has been increased.

Introduction

　FRAM has the features of both a

ROM and a RAM, and is a non-volatile

memory. It has the features of low

power consumption, a large number

of read/write cycles, and a fast write.

The newly developed 1Mbit FRAM

“MB85RS1MT” and the 2Mbit FRAM

“MB85RS2MT” are both serial memories

with SPI interface (Serial Peripheral

Interface). Until now, the maximum

density of Fujitsu's serial memories

was 256Kbit, but now it has become

possible to offer larger density products

to customers wanting memories with

density of 1Mbit or higher.

　 Further, as FRAM with ser ial

interface is compatible with serial

EEPROM (Electrically Erasable and

Programmable Read Only Memory),

and the customers currently using

EEPROM can gain faster speed of data

write and higher number of read/

write by simply replacing EEPROM with

FRAM. In this report, the advantages

offered by the 1Mbit and 2Mbit FRAM

products are described concretely.

　The specifications of MB85RS1MT

and MB85RS2MT are listed in Table 1.

Merits of using FRAMin applications

　Compared to conventional serial

memories, since FRAM offers the added

value of “low power consumption”, “a

large number of read/write cycles”, and

“a fast write”, it reduces the burden

of development and solves some

design problems that troubled product

designers, particularly regarding the

design of memory systems in the end

products. In addition, FRAM reduces

the risk occurring in the use of the end

products, minimizes loss and helps

reduce the total costs of the product from

New 1Mbit and 2Mbit FRAM products have been developed as the largest density serial interface FRAM provided by Fujitsu Semiconductor.These new types of memory are ideal for smart-meters, industrial machinery, and medical equipment. They contribute to increased performance, reduced power consumption, smaller size for the end products of customers, and help reduce the total costs including developing cost and running cost.＊FRAM: Ferroelectric RAM

being used as the memory for recording

data in measuring instruments of power

meters. However, it was not possible

to increase the frequency of recording

data due to the limitation in the

number of rewrite cycles of EEPROM.

For example, if the guaranteed usable

life of power meters is assumed to be

10 years, in the case of EEPROM with

guaranteed 1 million rewrite cycles, it is

only possible to obtain data once every

5 minutes. In contrast, in the case of

FRAM with guaranteed 10 trillion read/

write cycles, data can be obtained every

0.03 milliseconds, implying that the

data can be logged continuously.

　Since the data is recorded frequently,

if there is any sudden voltage drop or

power outage, an early detection of the

abnormality can be made by speedily

detecting an alarm.

　Further, in the case of EEPROM with

long data logging intervals, it is not

possible to record any increase in the

power consumption that has occurred

between the data logging points,

and hence there is the possibility that

the charges for the increased power

consumption are not collected. In

contrast with this, appropriate charges

can be collected in the case of FRAM,

which permit continuous data logging.

　Figure 3 shows the difference in

the data logging frequency between

EEPROM and FRAM for power meters.

　Thus, FRAM with guaranteed 10

trillion read/write cycles contributes

to a reduction of risk in the event of

an abnormality and the collection of

appropriate charges by data logging at

a high frequency.

Reduction of Countermeasuresagainst Sudden Power Failure

　Write times of EEPROM and FRAM are

compared in Figure 4. When the same

2Kbytes of data are written, compared to

a 5MHz maximum frequency of operation

of EEPROM, fast write is possible in

FRAM since its maximum frequency of

operation is 25MHz (comparison of 2Mbit

products). Besides, since in the case of

EEPROM the data write operation is done

after erasing the data in the memory cell,

a minimum write time (write cycle time)

of 5 ms to 10 ms is necessary. Compared

to EEPROM, in FRAM 8bytes of data can

be written in only a few microseconds

because write method is the same as

SRAM.

　Even when a sudden power failure

occurs during writing, the data can be

stored by fast write in the case of an FRAM,

but in the case of an EEPROM requiring

a long write time, it is necessary to add

countermeasures against power failure

such as a super capacitor or a low voltage

detection circuit in order to securely

protect the data being written.

　Furthermore, even when an abnormality

such as a power failure occurs, since

an FRAM is recording the immediately

previous data, a system restart operation

can be expected to be faster than in the

case of an EEPROM when the power

supply is restored.

Reduction of Total Costs

　The features of FRAM described so far

development up to running.

　Figure 1 shows the memory system

design concerns of design engineers of

a power meter, which is an example of a

target application, and solutions to the

concerns.

　Next, the features of FRAM and the

merits are described below.

FRAM Saves EquipmentPower Consumption

　FRAM non-volatile memories lead

to saving in power consumption of

the equipment, because FRAM does

not require a battery for retaining

data, unlike SRAM. Also, in the case of

EEPROM, power consumption becomes

large, because the data write current

is large and the write time is also

long. In applications such as power

meters required frequent data logging

and records, since the number of read/

write cycles becomes large, the power

consumption of EEPROM becomes high.

　In comparison, in the case of FRAM,

the power consumption becomes

small, because the data write current is

much smaller and also the write time

is shorter. In other words, power can be

saved by replacing the memory used

for data recording with FRAM.

　When the power consumption during

data write is compared between FRAM

and EEPROM of the same memory

density, an FRAM can save a maximum

of 92% of the power consumption of an

EEPROM (when 2Kbytes data write in 1

second).

　Comparison of the power consumptions

in EEPROM and FRAM is shown in

Figure 2.

Reduction of Risk andAppropriate Charge Collection

　Fujitsu's serial interface FRAM had

achieved to guaranteed number of

read/write cycles of 1 trillion times, and

the new 1Mbit and 2Mbit FRAM have

guaranteed number of read/write cycles

of 10 trillion times. This corresponds to

10 million times the number of rewrite

cycles of EEPROM.

　Table 2 shows a comparison of write

features of EEPROM and FRAM (2Mbit

product).

a single FRAM, not only the component

count of memory is reduced, but the

battery for data retention in an SRAM

also becomes unnecessary. Since the

size of the memory package itself also

becomes smaller by the replacing, it is

possible to reduce more than 90% of the

mounting area of the memory system

components. Because of this solution,

the customers have many advantages

that the end product is made smaller,

replacing the battery is not needed, the

power consumption is reduced, and the

component cost is reduced.

　Figure 6 shows a comparison of the

mounting area when a memory system

consisting of two memories is replaced by

a single FRAM product.

Lineup ofFRAM Products

　Figure 7 shows the lineup of serial

interface FRAM products of Fujitsu. By

addition of 1Mbit and 2Mbit FRAM

products this time, the SPI interface

products are available from 16Kbit to

2Mbit, and I2C interface products are

available from 4Kbit to 256Kbit.

Future Developments

　Since started mass production of

FRAM in 1999, Fujitsu Semiconductor

has continued to provide high quality

and high reliability products with stable

supply, and FRAM products have so far

found use in various applications such

as OA equipment, industrial machinery,

medical equipment, ATM, etc.

　Fujitsu will continue to make

progress in the development of FRAM

products in order to provide solutions

that improve the performance of end

products, simplify maintenance during

operation of end poducts, minimize the

risks that occur during the operation, and

contribute to reducing the total costs for

the customers. ■

lead to a reduction of the total costs to

the customers. The total costs here are

not only the development cost of end

product, but also includes various costs

that occur during the running of the

products, such as a meter or industrial

machine, etc.

　Figure 5 gives an image of the total

costs of power meters.

　The first feature of “low power

consumption” is directly linked to a

reduction of total power consumption of

equipment or instrument. In addition, in

the case of battery-operated equipment

or industrial machinery with a battery,

the number of battery replacements

becomes small, and not only the battery

components but also the personnel

expenses related to the replacement can

be reduced.

　Next, the “large number of read/

write cycles” minimizes the loss when

an abnormality occurs. In other words,

because of highly frequent data

logging, an alarm can be detected

almost in real time when an abnormality

occurs. Consequently, since the abnormal

state can be made to last only for a

short time, the loss of opportunities

in terms of money, personnel, and

time can be minimized. Furthermore,

since the unbilled electricity charges can

be reduced by minimizing the period

over which data could not be logged

in a measuring instrument (such as an

electricity, gas, or water meter), the loss

is not allowed to become large.

　Finally, the component cost can be

reduced since “fast write” makes a

measure against voltage drops or

power failures such as a super capacitor

unnecessary. In addition, even during

above mentioned power failures,

recovery can be speedy because the

immediately previous data is stored,

and hence the loss of opportunity is

suppressed to a minimum. Furthermore,

even in the worst-case scenario, by

securely protecting the data being

written, the loss of data is minimized, and

any increase in the compensation for

damages associated with the occurrence

of an abnormality can be prevented.

　As has been described so far, FRAM

contributes to minimized the total costs

by reducing the cost of development of

end product such as deleting the super

capacitor, reducing the cost of running

such as component cost of battery and

maintenance cost, and minimizing the loss

of opportunity and payment of damage

compensation in the event of a risk during

running.

What Large Density FRAM Can do

　Fuj i tsu has developed 1Mbit

and 2Mbit FRAM in answer to the

requirements for serial interface FRAM

products with features of low power

consumption and fast write speed and

density of 1Mbit or more and as described

above. These are expected to be used in

measuring instruments, such as smart

meters, that require large density non-

volatile memories, industrial machinery,

and medical devices such as hearing

aids, etc.

　In addition, in the case of industrial

machinery or medical equipment that

use two memories, an SRAM with

a battery for recording data and an

EEPROM for storing parameters and

programs, these two can be replaced

by a single FRAM product, thereby

integrating the two memories functions.

This memory solution is enabled because

the memory density of FRAM has

increased to 2Mbit. By replacing it with

MB9B120J Series

Overview

　Fuj i tsu ' s new, low-pin-count

microcontrollers are particularly

appropriate for customers who want

to implement motor control in a small

mounting area.

　The MCUs, which come with one

built-in multifunction timer unit, are

available in either an LQFP32 package

or a QFN32 package (5mm × 5mm). When

placed in the circuit board of a brushless

motor, the new microcontroller offers a

good price/performance ratio in a small

mounting area.

Features

Highly reliable, high-speed flash memory realizing the highest speed in its class

　The highly reliable, high-speed NOR

type flash memory installed in these

products can be accessed without wait

states at up to 72 MHz. This high-speed

memory access realizes the highest

processing capacity in its class and fully

utilizes the power of the CPU.

　Like previous products, the new series

is highly reliable, with an endurance of

100,000 write cycles or the capability

to retain data for 20 years. In addition,

the flash security function prevents

illegal reading of the program from

the outside, securing the customer's

software assets.

Set of Peripheral Macros Realize Highly Accurate Motor Control

　The new microcontrollers incorporate

the set of peripheral functions of Fujitsu's

FR family microcontrollers, which have

an established reputation for motor

control. Various peripheral macros

have been enhanced to support more

accuracte motor control. In particular,

a highly accurate and high-conversion-

speed, 12-bit A/D converter (±2.5LSB,

1.0μs conversion) exhibits its power

in applications such as the high-

efficiency inverter of white goods (home

appliances) and industrial systems. This

product is installed with one unit of the

A/D converter with a maximum of 8

channels.

　Because the MCU incorporates a quad

counter, the hardware can detect the

motor rotational position, a function

that was previously performed by

software) This reduces the load on the

CPU. Power savings can be achieved in

an inverter system by employing these

products.

Compatible with Various Power Supply Systems over a Wide Voltage Range with Low Power Consumption

　The FM3 fami ly can operate

under a wide range of power supply

voltages, from 2.7V to 5.5V. These

products are compatible with both

the 3V and 5V systems of OA and FA

equipment, white goods, and household

electrical appliances. In addition, these

microcontrollers use less power than the

higher-level, high-performance group

of products. The current consumption

is half that of previous products at the

same clock frequency.

of the MB9B120J series, and Figure 2

shows an example of the MB9B120J

series being used in an application. ■

MB9B520T / MB9B420T / MB9B320T / MB9B120T Series

Overview

　The FM3 microcontrollers use the Cortex-M3

global-standard, high-performance core. The

MCUs leverage Fujitsu's vast experience in

microcontroller development, and feature

the peripheral functions of the FR family,

which has gained considerable support

from the market over many years.

　At a high level, these MCUs balance cost,

performance and power consumption,

making them appropriate for a wide

range of applications. For example, this

group of products is appropriate for the

inverter control of white goods (e.g., air

conditioners, refrigerators and washing

machines) and in the human-machine

interface sections of household electrical

appliances. In addition, these products

can be used for the various types of motor

control used in office automation (OA)

equipment —such as printers and copy

machines— and can implement network

communication among industrial

equipment through their supported

Controller Area Network (CAN) functions.

Features

　These microcontrollers contribute to the

high efficiency and low power consumption

of white goods, OA equipment and

industrial equipment. Optimal solutions

are offered by incorporating high-speed

flash memory; CAN; a highly accurate,

high-speed 12-bit A/D converter; a

variety of timers; USB 2.0 Host/Function;

multifunction serial communication; and

support for a wide range of power supply

voltages (2.7V to 5.5V).

Highly reliable flash memory realizing the highest speed classin the industry

　An endurance of 100,000 write cycles

or a retention property of 20 years have

been realized in the highly reliable NOR-

type flash memory installed in these

products. The flash security function

prevents illegal readout of programs from

the outside, protecting the customer's

software assets.

Abundance ofCommunication Macros

　These microcontrollers have inherited

the proven communication functions of

the original core, and are also equipped

with a variety of serial communication

macros, including CAN, USB 2.0 Host/

Function, and multifunction serial

communication (UART/CSIO/LIN/I2C). The

MCUs can be used widely with devices

that use networks such as OA and AV

equipment.

SWEETS CAR Brings the Spring Breeze

Spring always comes suddenly.

One day you go outside and notice the softness of the air as it touches

your cheek. You might notice a faint, nice smell. On a day like that, have

you ever thought to yourself, “Spring has come?”

The moment you realize it, the world suddenly brightens.

We tried to make a “sweets car” that brings that spring breeze home.

The outside of the car is covered with light, sky-blue colored cream; the

inside is made up of heavy pound cake.

The classic image hinted at by the shape of the lamps and bumpers

adds a nostalgic, warm feeling. We’d love to drive a car like this in the

distance somewhere.
